I can't delete a birthday from Google Calendar

[Android Central Question]

Somehow a birthday got put into my Google calendar and there is no way to delete it. I checked my settings and I have unchecked birthdays from my contacts, and there is no delete button that shows unlike other events in my calendar. All I can do is open but no where to delete.

Welcome to Android Central! Which calendar is that birthday part of?
